Digital Overcurrent Relays, K2OC

[Features]
Digital Overcurrent Relay: Digital OCR simplifies protection coordination under each power company's jurisdiction.
• Five time-delay characteristics are selectable, facilitating protection coordination design.
• Two built-in instantaneous characteristics are included. The instantaneous three-stage characteristic operation value can be adjusted, increasing flexibility in protection coordination design.
• The 7-segment display shows measurement values ​​and relay control status, allowing for at-a-glance understanding of monitoring conditions.
• Changed settings can be temporarily displayed on the 7-segment display, improving work efficiency in dark areas.
• The operation value upon fault detection can be saved as an fault history, making it easy to narrow down the cause of the fault.
• An inspection contact has been added to the front, allowing relay operation testing without entering the power panel during inspection.
• The cylindrical body design makes it easy to replace conventional cylindrical body relays.
• The front cover can be opened left or right to match the layout of the panel equipment.
• The industry's first single-function protective relay that complies with JIS C4602 (2017) (according to our research as of December 2018)
